SPECIFICATION forming part of Letters Patent No. 679,520, dated July 30,1901. Application filed November 17, 1900. Serial No. 36,796. (Nomodel.)

To whom it may concern.-

Be it known that I, FREDRIOK D. STEPHENS, a citizen of the UnitedStates, residing at German Valley, in the county of Morris and State ofNew Jersey, have invented certain newand useful Improvements in Heaters;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawin gs, and to figures of reference markedthereon, which form a part of this specification.

This invention relates to a hot-water or steam heater, and refersprincipally to that class of heaters known as square heaters, beingbuilt up of heater-sections, which are assembled to constitute theheater.

The present construction of heater can be enlarged or reduced with easeand Without greatly increasing the cost of the heater, as the partsinserted or removed are substantial duplicates.

The object of the heater is to provide a square heater and containingvertical fiues and one that is practically self-cleaning and that canalso be cleaned from the outside with ease.

This invention also furnishes a heater of the square pattern thatcontains a magazine for fuel and makes the heater self-feedin g anddecreases the heating-surface to a very little extent.

The heater herein shown also supplies a large heating-surface and a freeand unobstructed circulation of water or steam, and the cost ofmanufacturing which is small.

The construction of my new form of heater is shown in the accompanyingviews, in which- Figure 1 is a side View, and Fig. 2 a longitudinalvertical section, of the same. Fig. 3 is a part elevation and partcross-section of the heater, the section being taken on line 3 3 in Fig.2. Figs. 4 and 5 are a face and bottom view of one of theheater-sections. Fig. 6 is a section of a heater with the sectionsassembled, with the omission of the magazine. Fig. 7 is a bottom view ofthe sections. Fig. 8 is a perspective View of the plates inclosing partof the smoke-chamber.

In said views, 1 illustrates the base of the heater, which is madeeither integral or with removable side and rear plates. The grate 2 issupported by said base and is preferably made with a removable frame andgrate-bars, so that when a heater is changed in size the frame can beremoved and a new frame inserted, with its requisite number ofgratebars. On said base are arranged the heatersections 3, which areshown detached in Figs. 4, 5, and 7, and consist, essentially, of theleg portion 4, the bridge portion 5, and the overhang 6, as will beevident from the drawings. The bridge portion 5 may have a corrugatedsurface or plain, as desired, and is reduced in width as compared withthe leg and overhang to allow for the circulation of heat from thefire-box formed by the legs 4, and the overhang is provided on itsopposite sides with cut-away portions or grooves 7, that may be of anyconfiguration in section, which when the sections are assembled form theflues 7, as will be seen from Fig. 7. The leg portion 4 is finished onat its top with the pointed end 8, and so forms with the bridge portionand overhang the connecting-flue 9 between the flue 7 and space betweenthe bridge portions. The heater sections are preferably provided withperforations or holes 10 in the leg portions 4, near the bottom thereof,and the holes 11 at the top to permit the ready circulation of theheating medium, and at the same time may be used for the insertion ofthe retaining or holding bolts 12 and 13, respectively, which serve tohold the said heater sections together by means of the nuts 14; butthese bolts may be disposed elsewhere and any form of securing means maybe used. Secured to the bottom of the overhang and resting on the top ofthe base 1 are the plates 15, which are placed on the sides of theheater and are brought together at the rear of the heater by means ofthe lines 16 to connect with the smoke-pipe 17. The rear section of theheater is provided, preferably, with an opening 18, which connects withthe smoke-pipe 17 by means of the pipe 19, and the said pipe 19 isprovided with a damper 19, the use of which will be describedhereinafter. The front section is provided with the usual fire-door 20,and both the front and rear sections are devoid of any The water spacereaches bridge portion.

from the top to the bottom for the full width, and the sections therebycompletely inclose the fire-box.

The three front sections of the heater are shown in Fig. 2 as beingprovided with the openings 21, which form a magazine for the fuel thatis supplied to the heater. The pocket 22 is secured to the front of theheater by means of a nut on the bolt 13 and increasesthe capacity of themagazine and allows of its beingfilled. The pocket 22 is provided withalid 23, which has secured thereto a chain or similar medium 2% toconnect it with the damper 19* by means of the pulleys 25, which may beattached to the heater, as shown, or to the ceiling overhead. is openedfor inspection or the filling of the magazine, the chain releases thedamper 19 and causes a direct draft to be established from the fire-boxto the smoke-pipe and no gases will escape into the house, and whenthedoor is closed the damper will again be closed, as will be evidentfrom Fig. 1.

The usual form of draft-door and checkvalve regulator is shown inconnection with the heater, and the water or steam gages are of the'usual form of construction.

The connecting portion 16 of the smokecha-rnb'er is inclined upwardlyand inwardly to the center of the rear section and is connected to thesmoke-pipe 17, which is preferably cast in one piece with the pipe 19and is braced at the top by means of the brace 26, secured to the bolt13, as will be understood.

The smoke-chamber plates 15 are preferably made in one piece to fit asmall-sized boiler, and if alarger-sized boiler is required a plate tofit the width of the section inserted is attached, as shown in Figs. 1and 8, and so if a heater is to be reduced the plate attached to theremoved section can be withdrawn with itand the remaining sections drawntogether. In like manner the side pieces of the base can be sectionallyconstructed to admit of its enlargement or contraction, or the sides ofthe base and the smoke-chamber inclosur'e can be entirely constructed ofsmall plates, as desired. In the bottom of the smoke-chamber plates canbe placed the openings 27, which are provided with the lids 28, saidopenings allowing the cleaning of the fiues '7, and clean-out doors atthe ends of the smokechamb'er insure the easy cleaning of its interior.

The outlet-pipe 29 and inlet-pipe 30 can be suitably placed, but arepreferably placed as shown, the rear section being bulged to allow of aquicker distribution of water. The discharge-cock 31. may be placed inthe inletpipe or any other convenient point of the heater.

In square heaters as previously made the sections after being assembledhave formed horizontal fines which carry the heat back and forth andalso cause interruptions in the circulation of the water. The horizontalfiues catch the soot and ashes on the lower fore they require constantcleaning.

When the door 23 side, and in a short time the layer of these productsof combustion becomes partly an insulation from the heat, and coupledwith the fact that the heat naturally clings to the upper side of suchfines the bottom of the fiues is contributing no heating-surface. There-In the present construction the fines being vertical the products ofcombustion have little chance of attaching themselves, the inside of theheater-i. 6., between the bridge portionspractically cleaning itself, assoot, 850., will fall from them in the fire and be consumed. The fines 7are also not apt to become very dirty, but are easily cleaned throughthe holes .in the smoke-chamber, as will be evident.

The steeple-point on the leg portion prevents the lodging of soot atthat point. I have thus devised a cheap simple heater of the squareclass with vertical dues and a magazine,which 'is easily cleaned, aheater that can be en- I larged or reduced with sections in duplicate, 1and one in which the circulation of the water is unobstructed byhorizontal interruptions.

The sections of the heater are closelyjointed all around, with theexception of the flue portions, and the outside surface requires nometallic casing, as the fines communicate only with the smoke-chambers.

That portion of the heater above the smokechamber may be covered withasbestos, asbestos-cement, or any other non-heat-c'ond ucting material.

Of course I may make minor changes in the details of constructionwithout departing from the limits of my invention, and I may dispensewith the magazine and make a surface burner.

Having thus described my invention, what I claim is- 1. A heater,consisting of heater-sections, said sections consisting of a hollow legportion, a bridge portion, an overhang, and cutaway portions on saidsections to form fines between said sections, and a smoke-chamber oneach side of said heater under said fiues, substantially as described.
